Enventure’s single-joint, solid steel, expandable casing patch is the first choice for operators who need a permanent, inexpensive casing patch solution that reliably restores well integrity.

While Enventure has always been known for robust, reliable SET® expandable products, this simpler approach to re-establishing casing integrity means you get the same quality and reliability in a new, lower cost solution for sealing unwanted perfs, casing leaks or reinforcing casing.

The solid steel expandable casing patch has elastomeric bands attached to the top and bottom; it is deployed on the work string or coil tubing. Once expanded, the elastomers anchor the system to the base pipe and the shoe is milled out. This simple and effective design provides a quick, inexpensive, and permanent seal while reinforcing short casing sections, restoring well integrity and prolonging the life of the well.
